Summary In this paper, we study the multicast capacity of a large scale random wireless network. We simply consider the extended multihop network, where a number of wireless nodes v(i)(l <= i <= n) are randomly located in a square region with side-length a = root n, by use of Poisson distribution with density 1. All nodes transmit at constant power P, and the power decays along path, with attenuation exponent alpha > 2. The data rate of a transmission is determined by the SINR as B log(1 + SINR). There are n, randomly and independently chosen multicast sessions. Each multicast has k randomly chosen terminals. We show that, when k <= 01 n and n(s) >= theta(2)n(1/2+beta), the capacity that each multicast session can achieve, with high probability, is at least C(8) root n/n(8)root k, where theta(1), theta(2), and c(8) are some special constants and beta > 0 is any positive real number Our result generalizes the unicast capacity [3] for random networks using percolation theory.
